Commen= t # 5 on bug 10039= 5 from Andy Furniss 
Seems, I've found it. Many skips to work around vega build iss=
ues, but I got
past them and got a bad then good.

Further skips then due to startx hangs with dmesg logging ring test fails o=
n 3
to 8.

Fortunately it then worked and only gave two choices one vega and -

possible first bad commit: [91561a39fa74e79b88e0e9d70f3072501c8df2ce]
drm/amdgpu: get display info from DC when DC enabled.

This cleanly reverts from head - and the issue is gone with it reverted.
